Answer:
The given blank can be filled with pleomorphic.
Explanation:
Pleomorphism, in microbiology, refers to the tendency of some of the microbes like bacteria to change their size or shape in response to the environmental conditions. In the context of bacteriology, pleomorphism is based upon the change in the shape or size of the cell, in spite of a change of shape as considered previously.
Answer:
C. Yes, Trisha should have a group of frogs in her experiment that is not exposed to any pesticide at all
Explanation:
The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study (in this case, the effect of pesticide) from the results that might be a consequence of other factors. The control group must be selected from the same population of the treatment group. All the groups must be similar in every variable that might influence the results, except for the study treatment.
- Control group: Frogs that are not exposed to any pesticide
- Treatment one: Frogs exposed to a certain concentration of pesticide
- Treatment two: Frogs exposed to an increased concentration of pesticides ...
And so, the number of treatment groups will depend on the different concentrations of pesticides Trisha wants to study.
All groups must belong to the same population and of course, to the same species. They must also be exposed to the same variables, excepting for the pesticide variable.
Answer: 1. a change in an individual's body in response to changes in environmental conditions
Explanation:
An adaptation can be defined as any alteration or change that occurs in the structure and function of the organism that results due to natural selection. An adaptation generally occurs when the organism is exposed to an unfavorable environment.
The adaptation makes an organism better suited to survive in an unfavorable environment.
The changes in the environment favor the changes in the body of living individuals.
PCR multiplies the DNA in 25 to 75 cycles
Answer:
a. True
Explanation:
Proteins are biopolymers composed of amino acids that appear in chains. These amino acids are formed by peptide bonds. Due to the functions they carry out, proteins are essential for the existence of life. Proteins can be found in both animals and vegetables. In animals, there are proteins that help protect the body, others are in charge of regulating metabolism. On the other hand, in plants proteins participate in cell division processes, membrane transport, catalysis of biochemical reactions, photosynthesis and respiration processes, synthesis of sugars, starches, and other compounds.
